`APPARATUS FOR VMEYLT'ING ANCHOR-ICE.

srEcIrIeMIorI` forming perrorv Letters Patent 4rrafaraeoi, dated Jungle,1883.

Application ined February-23,1853. (No modem l useful Improvement inMeans for Removing Anchor-Ice, of which the following is a descrip tionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, reference being had to the accompanying drawings, forming a partof this specication, in which- Figure l is an isometrical perspectiveview, representing the apparatus in use; Fig, 2, 'a sideelevation,representing it detached or not in use; and Fig. 3, asectional view.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates more especially to means for removingthe anchor-icewhich forms or accumulates at or near the screens of water courses oraqueducts and in the flumes or gateways of mills, and it consists,first, in a jet of steam applied under water directly to the ice bymeans of a pipe, hose, or any other proper appliance for the purpose;secondly, in a ilume, canal, aqueduct, or water-course provided near"its gateway or screen with a steam pipe or pipes arranged in such amanner as to enable steam to be brought into direct contact with theanchor-ice under water; and, thirdly, in an apparatus having a novelconstruction and arrangement of parts, as hereinafter more fully setforth and claimed, by which a more effective device for this purpose isproduced than has heretofore been employed.

It is ``well known that a great deal of trouble exists in all coldclimates, arising from the formation or accumulation of anchor-ice iniiumes, canals, aqueducts, and other water-courses, more especially ator near the fine screens usually employed for straining thedrinking-water supplied to towns and cities by means of aqueducts, theice frequently choking up the screens to such an extent as to render itdifiicult to obtainaproper supply of water. My improvement is designedto obviate this difficulty, and to that end I make use of means whichwill be readily understood by all conversant with such matters from thefollowing explanation, its eX- treme simplicity rendering an elaboratedescriptionunnecessary. k

In the drawings,'A represents theiaqueduct or fiume, and B the screen orstrainer. Arranged near the screen, on its upstream side, there is aframe-work, C, as best seeninFig. 2, the frame consistingof the 'sidepieces, D E, and crosspieces F GII I, composed of steam-pipes properlycoupled together; This frame-work is preferably arranged to slidevertically in the ways d d, ,enabling it to be readily removed in thesummer or whenever occasion requires, and is represented in Fig. 1 aspartially elevated. A steam-pipe, J, connects the frame with a boilerfor supplying steam, and branching from this there is a pipe, K, for usein combination with the hose L, which is provided with the `doublenozzle M. At the sides of the pipe J ,where it connects with the pieceF, there are two stopcocks,Z a, and there are also stop-cocks f g h,arranged respectively at the ends of the pieces G H I, as shown; but thestop-cocks may all be dispensed with, if desired. The pieces F G H I areperforated on their upstream sides forthe Vemission of steam, this beingpreferable to having them perforated on' all sides, as it tends toconcentrate or direct the steam onto the ice to the' best advantage andwith the least waste.

In the use of my improvement the frame O is inserted in the ways d d andpushed down to the bottom of the aqueduct, after which itis properlyconnected with the induction-pipe J. Steam is then let into theapparatus, and, passing into thepiecesrl G I-I I, will be emittedthrough the p erforations i and brought into direct contactwith the ice,which will be rapidly melted, the unmelted ice being carried bythecurrent down against the frame to take the place of that melted untilthe entirebody is dissolved.

The object ofthe stop-cocks in the frame-work is to control the steamand direct it to any point desired, or to use it in every alternatecrosspiece.

The nozzle M is provided withtwo dischargeoriiices, j; but a greater orless number may be employed, if preferred. The nozzle is also providedwith a socket, N, and handle T, (a section only being; shown,)the handlebeing of sufficient length to enable vthe nozzle to be pushed downto thebottom of the aqueduct and manipulated to bring it into contact with allIOO parts of the screen in directing the steam onto the ice.

The hose may be used either with or without the frame-work when properlyconnected with a boiler or pipe for supplying steam, but is preferablyused as auxiliary to the rest of the apparatus.

It will be obvious that the' framework may be permanently applied orarranged to be read ily detached, and may be provided with any number ofcross-pieces, if preferred. I do not, however, .wish to be understood asconfining myself to the use of live steam, as exhauststeam may be used,if desired, or to the employment of any special number or arrangement ofpipes, or to perforating them on one side only, as these features may bevaried greatly without departing` from the spirit of my invention.

may be directed into one or more of said pipes,

substantially as described.

3. An aqueduct or flume provided with a screen,withvertical ways infront thereof, and with a frame of steam-pipes vertically adjust able insaid ways, substantially as described.

4. In an apparatus for removing anchor-ice from watenways, asteam-nozzle provided with a pipe connected with a flexible steam-supplypipe, and with a socket having an elongated handle, whereby the nozzlemay be operated beneath the water, substantially as described.

5. n a device substantially such as described, the framework C,consisting of the perforated pieces F G H l and sides D E, incombination with the pipe J, substantially as set forth.

6. In adevice substantially such as described, the framework C, providedwith the stopcocks Z a f f/ 71 substantially as and for the pur posedescribed.
